As the paint is failing, I've noticed a bunch or hairline cracks.

Is this something normal for stucco or something to be concerned with.
Wondering if this needs repair prior to applying new paint or just using paint with elastomer.

Were it I, I would use a wedge-shaped tool to create a "V" grove, and it doesn't need to be deep and with an aggregate caulk and a sponge trowel, for blending the texture, prime and paint.

Some of the exterior paints will bridge the cracks nicely.

What tool would you recommend to creating the "V" groove? I'm thinking multitool or die grinder since a hand tool would take a lot of effort.

They make a tool for that, however, I just use an old style can/bottle opener, because the grove isn't that deep.
